Multi-Input/Multi-Output Sensitivity Points Tuning.

Abstract

Periodic tuning is a virtually essential aspect in the maintenance of almost any physical plant. One method of such tuning is that known as sensitivity points turning method. The theory of this method and application to single-input/single-output (SISO) systems have been fairly well developed. This thesis investigates the application of sensitivity points turning concepts to the tuning of multi-input/multi-output (MIMO) systems. The concept of sensitivities in feedback systems was originally introduced by Bode in the 1940's. Methodologies for using sensitivity information for optimal tuning of system parameters date back to the late 1950's and early 1960's and include work done by Meissinger, Margolis and Leondes, and numerous others. These works all involve the use of system sensitivities in order to provide a searchless means of computing the gradient of a given cost function which possesses some extremal value that is related in some way to some desired characteristic performance of the system under tuning. Included in this class of optimization techniques are the iterative parameter optimization techniques.
